Oil heat system technicians install, repair and maintain all types of oil-fired domestic and commercial appliances, equipment, components and systems. On new installations, they may design, assemble and install the heating and ventilation systems, install oil burner components such as control devices and associated wiring, install fuel supply systems and connect the plumbing to mechanical and electrical systems. They may also install, maintain and repair wood/oil heating systems.

Oil heat system technicians work in the residential, commercial and industrial sectors. They may be self-employed or employed by heating, ventilation and air conditioning (HVAC) installation and service companies.

Service calls and emergency calls may take place anytime: days, evenings or weekends. Full time and seasonal employment opportunities are available.

Oil heat system technicians must have good mechanical aptitude, problem solving skills and good customer relations skills. A good understanding of basic electrical/electronic theory and The House as a System is also required. They may give cost estimates for required work and explain the operation and maintenance of appliances and systems.

This analysis recognizes similarities or overlaps with the work of refrigeration and air conditioning mechanics, gasfitters, plumbers and sheet metal workers.

Experienced oil heat system technicians may advance into supervisory and management positions or move into self-employment.

Occupational Observations

Oil heat system technicians must continually upgrade their skills to become proficient with new products and equipment introduced into the industry. Testing efficiencies are more easily realized with the introduction of computerized sensors, electronic and digital controls.

Technological changes and stringent new regulations have forced oil heat system technicians to upgrade their skills and constantly apprise themselves regarding environmental legislation. The increasingly complex and stringent environmental laws, especially regarding oil storage units, are having a major impact on the occupation. The mechanic must recognize potential hazards and react to dangerous situations. The skill of containment is becoming more critical and environmental incident reporting procedures are evolving areas for the mechanic.

Customers continue to ask the oil heat system technician for more input and advice on choosing a highly efficient and cost effective system.

A move to alternative fuel sources continues to make a major impact on the oil heat system technician trade. The mechanic must access specialized training in order to become proficient in the delivery, storage, distribution and combustion of such fuels with specific emphasis on safe handling and system operation.
